Screening American independent film
No full textThis indispensable collection offers 51 chapters, each focused on a distinct American independent film. Screening American Independent Film presents these films chronologically, addressing works from across more than a century (1915-2020), emphasizing the breadth and long duration of American independent cinema. The collection includes canonical examples as well as films that push against and expand the definitions of independence. The titles run from micro-budget films through marketing-friendly Indiewood projects, from auteur-driven films and festival darlings to B-movies, genre pics, and exploitation films. The chapters also introduce students to different approaches within film studies including historical and contextual framing, industrial and institutional analysis, politics and ideology, genre and authorship, representation, film analysis, exhibition and reception, and technology. Written by leading international scholars and emerging talents in film studies, this volume is the first of its kind. Paying particular attention to issues of diversity and inclusion for both the participating scholars and the content and themes within the selected films, Screening American Independent Film is an essential resource for anyone teaching or studying American cinema
Evidence of Langmuir Mixing Effects in the Upper Ocean Layer During Tropical Cyclones Using Observations and a Coupled Wave-Ocean Model
Get PDFMixing of the ocean beneath tropical cyclones (TC) cools the surface temperature thereby modifying the storm intensity. Modeling studies predict that surface wave forcing through Langmuir turbulence (LT) increases the mixing and cooling and decreases near-surface vertical velocity shear. However, there are very few quantitative observational validations of these model predictions, and the validation efforts are often limited by uncertainties in the drag coefficient (Cd). We combine EM-APEX and Lagrangian float measurements of temperature, salinity, velocity, and vertical turbulent kinetic energy (VKE) from five TCs with a coupled ocean-wave model (Modular Ocean Model 6—WAVEWATCH III) forced by the drag coefficient Cd directly constrained for these storms. On the right-hand of the storms in the northern hemisphere, where wind and waves are nearly aligned, the measured VKE is consistent with predictions of models including LT and 2–3 times higher than predictions without LT. Similarly, vertical shear in the upper 20 m is small, consistent with predictions of LT models and inconsistent with the large shears predicted by models without LT. On the left-hand of the storms, where wind and waves are misaligned, the observed VKE and cooling are reduced compared to those on the right-hand, consistent with the measured decrease in Cd. These results confirm the importance of surface waves for ocean cooling and thus TC intensity, through both Cd and LT effects. However, the model predictions, even with the LT parameterization, underestimate the upper ocean cooling and mixed layer deepening by 20%–30%, suggesting possible deficiency of the existing LT parameterization
Assessing the morphodynamic response of a New England beach-barrier system to an artificial reef
No full textAs a result of climate change and the ensuing accelerating sea level rise, the Ninigret Trustom Pond beach barrier system, located along the southern shore of Rhode Island, USA, has become increasingly vulnerable to tropical storms, hurricanes, and Nor\u27easters affecting the region. In this work, we explore the ability of a segmented artificial reef (AR) to protect the Ninigret Trustom Pond beach barrier system, by reducing the incident wave energy and ultimately the beach erosion. A set of nine AR concepts are selected, which are predicted to be accretive based on Ranasinghe et al.’s (2010) design criterion (RVB), extended by van der Baan (2013) to apply to segmented submerged breakwaters. The effectiveness of each concept is then assessed through numerical simulations, for both average wave climate conditions and storm events, with and without sea level rise, using the 2D morphodynamic model XBeach. The AR concepts are evaluated based on their ability to reduce coastal erosion during the storm events, including with a near future sea level rise of 0.31 m (scenario based on local prediction by 2050 relative to 2020 following the intermediate NOAA scenario), while ensuring a slightly accretive behavior in average wave conditions. The reduction of the coastal erosion during the storm events is quantified by comparing the subaerial eroded volume at the site, with or without sea level rise, when implementing each of the nine pre-selected AR concepts. While all concepts are found to protect the shoreline during storm events, including with the 0.31 m sea level rise scenario, four of the nine AR concepts, pre-selected to be accretive based on the RVB criterion, are found to be erosive in average conditions. Assuming a given submergence level, the distance to the shoreline and the AR lateral confinement ratio, LC, (gap width to length ratio of the segments) are the main controlling parameter

Gaseous and soil OCPs and PCBs along the Indus River, Pakistan: spatial patterns and air–soil gradients
Get PDFThis study presents first-hand information on the occurrence of persistent organic pollutants (POPs) in the ambient air and surface soil along the Indus flood-plain, Pakistan. The sampling campaign was conducted at 15 site locations during 2014–15, along the Indus River (approximately 1300 km). Composite surface soil samples (N = 15) and passive air samples (N = 15) were collected for the estimation of gaseous POPs as well as air–soil exchange to evaluate the POP emission and distribution or dispersion patterns, source tracking, and contribution of the local and regional sources towards POP accumulation in the Indus River system. Among the studied POPs, levels of DDTs and PCBs were noticeably higher in ambient air (50–560 and 10–1100 pg m−3) and in soil (0.20–350 and 1.40–20 ng g−1), respectively. Regarding the spatial patterns, higher DDT concentrations (ng g−1) were detected in the air and soil samples collected from the wet mountain zone (WMZ) (p \u3c 0.05), followed by the alluvial riverine zone (ARZ), low-lying mountain zone (LLZ), and frozen mountain zone (FMZ). The PCB data did not exhibit significant differences (p \u3e 0.05) for the air samples, while PCB concentrations were significantly higher (p \u3c 0.05) in soil from the LLZ, which may be associated with rapid urbanization and industrial activities in this area. The air–soil exchange of DDTs and PCBs showed net volatilization at most of the studied sites except for a few samples from the FMZ and WMZ. Results of this study about air–soil exchange gradients indicate the long range regional atmospheric transport (LRAT) of POPs to the colder areas (FMZ) of Pakistan, where these act as a secondary source of POPs in these areas
Toward a better understanding of coastal salt marsh mapping: A case from China using dual-temporal images
No full textCoastal salt marshes suffering from anthropogenic coastal development and sea level rise have attracted much attention because of their capacity for carbon sequestration and global climate change mitigation. Accurate mapping of coastal salt marshes is always the first step for their protection, management, and restoration. The inherent complexities of vegetation, dynamics of tides, and anthropogenic disturbances pose challenges for remote sensing-based approaches. Existing studies have utilized phenology information and various black-box algorithms to reduce misclassifications. However, the approaches with dual-temporal images containing phenology information have suffered from inefficiency; the misclassifications have been objectively post-processed rather than considered in the method design, and the tacit knowledge of the trained black-box models has not been revealed. To address the above issues, we proposed a new approach with solid improvements in dual-temporal image construction, misclassification processing, and tacit knowledge analysis, including an efficient method to synthesize dual-temporal images based on the common divisor of the green-up season or senescence season resulting from latitudinal gradients in narrow coastal areas of China, a detailed classification scheme by interpretation of iteratively collected samples, and a key decision rule approximating the trained model. We applied the approach to Sentinel-1/2 images and DEM data, thus deriving a 10-m resolution coastal salt marsh map of China with an overall accuracy of 92.5%. A qualitative comparison showed that the map produced in this study was fitted well with actual salt marsh distributions, resulting in improved accuracy when compared to recently generated maps. The most important contribution is that the overall nature of the trained model observed from the training samples was approximated by a four-feature decision rule following the principle of explainable artificial intelligence, i.e., B8senescence/B4senescence \u3c 2.06 & B4green/B8green \u3c 0.78 & B12green/B11green \u3c 0.72 & elevation \u3c 2.13, and thus established a new potential classification mechanism for dual-temporal black-box algorithms, i.e., the water signal was covered up by flourishing vegetation, but the situation changed when vegetation withered. This study not only generates an accurate coastal salt marsh map at a national scale but also provides a classification mechanism for dual-temporal image-based coastal salt marsh identification and mapping
I think it\u27s biblically wrong, but temptation gets the better of me : A survey on out-of-control sexual behavior in a Christian cohort of men in the UK
Get PDFThe current study aims to better understand influences on men within the UK Christian community on their engagement with pornography and prostitution. The authors utilized the Carnes (2012) survey to examine the landscape of sexual knowledge and behaviours, and to identify symptoms, and the propensity towards, “out-of-control sexual behavior” among participants. Data from a survey sent to the Christian community through church networks and word of mouth was used for this study. Of the 491 men who participated, the majority (94%, 460) described their personal Christian faith as “strong.” Despite the Christian faith community\u27s moral code of conduct, the survey results showed a gap in self-awareness and understanding of members’ thoughts, beliefs, and conduct. Although almost three-quarters (74%, 361) of participants viewed pornography negatively, nearly half (45%, 220) admitted to using pornography at least occasionally. Many participants (31%, 152) indicated that they learned about sex through watching pornography. The survey also revealed that 10% (51) of participants had engaged with a prostitute for sex. Additionally, 21% (105) of participants believed that erotic massage was not prostitution. Using the Carnes (2012) framework, the survey found that over half of the survey participants (53%, 258) had a propensity towards “out-of-control sexual behavior”. In relation to the church, more than half (55%, 268) of participants knew other Christian men who used pornography, and 25% (125) feared church discipline if they shared their use of pornography and prostitution. These results suggest that more programs and information are needed within the Christian community to build a culture of trust and accountability among members regarding sexual issues
Seafood consumption during harmful algal blooms: The impact of information regarding safety and health
Get PDFHarmful algal blooms (HABs) can cause massive fish kills all over the world. However, some commercially caught species are safe to eat. The fish safe for consumption are vastly different from the fish that wash up on shore. Prior research finds this difference in edibility is mostly unknown by consumers, and that the misperception of unhealthy and unsafe fish is the dominant paradigm. To date, there has been minimal research on the effect of disseminating this information regarding seafood health to consumers, and how consumption habits would change during a bloom. We implement a survey that presents respondents with information explaining the health and safety of certain commercially caught seafood during a HAB, specifically red grouper. It is a particularly popular, large, deep-sea fish. Our results suggest that respondents receiving this information are 34 percentage points more likely to say that they would be willing to consume red grouper during a bloom, relative to consumers who were not provided this added information. Prior knowledge of this information suggests long-term outreach programs may be more effective than last minute “point of sale” information campaigns. The results demonstrated the importance of correct knowledge and awareness regarding HABs, as it pertains to efforts to stabilize local economies dependent on seafood harvesting and consumption
Post-emergence movements and habitat use by hatchling diamondback terrapins
No full textDiamondback terrapins (Malaclemys terrapin) inhabit estuarine environments, and adult females typically nest in coastal uplands. Hatchlings emerging from nests overwinter on land and in coastal salt marshes, but the proportions that use each land cover type is not well documented. From 2019 to 2021, we tracked movements and habitat use of hatchlings post-emergence to determine the importance of upland overwintering sites to a terrapin population in Rhode Island, USA. In late summer and early fall, we attached a radio-transmitter and passive integrated transponder (PIT) tag (n = 46) or only a PIT tag (n = 132) to carapaces of hatchlings emerging from nests. From August to June, we tracked the hatchlings via radio-telemetry and a sweeping PIT tag antenna, successfully documenting the fates of 46.6% of them (n = 83). This group included 23 hatchlings that overwintered in the upland, 11 hatchlings that moved to the salt marsh in fall, 46 predated hatchlings, and 3 hatchlings dead from unknown causes. Upon emergence from their nests, 68% of hatchlings dispersed toward water and 32% of hatchlings dispersed away from water. In the uplands, hatchlings typically overwintered within about 2 m of habitat edges. Movement in the uplands peaked from late August to early October, then ceased until hatchlings re-emerged in late April through early June. To protect terrapins, we recommend limiting the use of heavy equipment (e.g., mowers, tillers) in vegetated uplands near nest sites, and scheduling vegetation management for colder months (Nov–Mar in New England, USA) when hatchlings are inactive
